ALVIN DAVIS PUFFER, OF MEDFORD, ASSIGNOR TO A. D. PUFFERS SONS,

OF BOSTON, MASSACHUSETTS.

FAucET.

SPECIFICATION forming part of Letters Patent No. 318,801, dated May 26, 1885.

Application filed October 14, 1884.

To all whom it may concern:

Be itknown that l, ALT-1N DAVIS PUFFER, a citizen of the United States, residing at )Iedi'ord, in the county ofMiddlescX and State of Massachusetts, have invented certain new and useful Improvements in Faucets; and I do hereby declare the following to be a. full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains tomake and use the I plate.

In my method I protect the parts by a covering of noncorrosive material of such thickness that it remains intact under the ordinary wear of the plug and case, the portions of said plug and case not exposed to the liquid being of muchharder metal than the protecting-plates, thereby constituting bearings of sufficient hardness to allow of long use of the faucet and protect the non-oxidizing metal from wear.

In faucets where the plug makes but a par tial revolutionthat is, less than half a turnthe protecting metal may be applied only to the portion of the body of the faucet exposed to the liquid. In other instances the pro tecting metal will extend entirely around the plug.

The drawings accompanying this specification represent in Figure 1 a vertical andin Fig. 2 a horizontal section on line y 3 of a single or ordinary faucet containing my invention, while Fig. 3 is a vertical and Fig. 4 a horizontal section on line .r x of a double or compound faucet so furnished. Fig. 5 is a section of part of the case of the single faucet. Fig. 6 is a view of the compound metal strip, to be explained.

I11 Figs. 1 and 2 the body or case of the (No model.)

faucet is shown at A, its plug at B, its cap at O, the liquid-way of the case being shown at a, and of the plug at b. In this instance the plug describes less than half a revolution; hence the protecting metal plate, which is shown at D, need extend but partiallyaround the interior of the case, as shown by heavy black line in Fig. 2. In applying this plate of protecting metal (which I prefer to make of pure silver) a good method is to counterbore the interior of the case from the top, as shown in Fig. 5 at c, and insert the protecting-plate D in the form of a tube in the lower part of the counterbore. The upper part of the counter is filled with a ring, E, of the same metal as the body or case A, and this ring E, 6 to obtain desired strength, is preferably of considerably greater thickness than the plate D. The tube D and ring E- may be secured firmlyin place by the method known as pure tin sweating.

In putting my invention into practice a good way to proceed in making the single faucet would be to employ two strips, D D, of metal, of considerable length, (see Fig. 6,) one, D, of practically the same material as the case of the faucet, and the other, D, of silver orother non-corrosive metal, and braze the edges of these strips together. The width of the compound strip G is such as to form a tube to fill the lower part of the counterbore c, and a piece of the proper length is to be cut from the strips for each faucet.

In Figs. 3 and 4 of the drawings the two plugs of a combination-faucet are shown, the outer one at A and the inner at B, while the outer case or body of the faucet is shown at H.

The liquid way or port of the plug A is shown at A, and of the plug B at'B.

The liquid-passages of the outer case, H, adapted to operate with the port A, are shown at a a, &c., as in this instance, extending radially entirely about such case; hence it is essential that the port of the plug A opposite such passage shall be provided with a protectlug-plate extending entirely about the outer periphery of the said plug A. This plate is in the form of a tube, F, of non-corrosive metal,inclosing and secured to the lower part of the plug A. In the present instance the inner plug, B, has but a short movementthat is, one similar to the plug B of Figs. 1,2, and 3. For this reason the protecting-plate in this case may be made and applied as thus shown in Figs. 1, 2, and 3.

As before stated, the non-corrosive metal plate or tube F is presented to the action of the liquids, thereby avoiding injury to the latter, while the remainder of the outer periphcry of the plug is composed of a hard metal to resist wear.

In all these forms the silver plate faces the outlet of the way or ways.

I am aware that it is not new to make a faucet-plug wholly of non-corrosive material; also, that it is not new to provide a faucet with a lining of tin, zinc, or other not easilyoxidizable material facing the liquid-ways of the plug; also, that it is not new to make an interior lining of the faucet from non-corrosive white-metal, the same being a mixture of tin, nickel, and regulus of antimony. I do not claim any of these devices; but,

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A faucet provided with a silver protecting-plate, the latter being arranged facing the outlet of the liquidway, substantially as set forth.

2. In combination with a faucet-plug, asilver protecting-plate on the inside of the faucet-ease, arranged facing the outlet of the liquid-way b of the plug, substantially as set forth. I

3. A protecting-plate, D, set into the counterbored inner face of a faucet case facing the liquid-ways of the plug, in combination with the ring E, which is set into the same counterbore and holds said plate in place, said ring being soldered to said faucet-case, sub stantially as set forth 4. A faucet-plug of hard metal, provided with a countersunk plate or plates of non-corrosive metal, which are presented to the liquid for the purpose of protecting the body of said plug, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
